fThis invention relatesto attachment for braces and'an Object of theinvention isto provide means whereby a brace can operate in corners,narrow places and other restricted 6 areas where the sweepof theordinarybrace would not permit its use.' I

1 Another feature of the invention is to provide an attachment thatisadaptable for receiving screw driving attachments, socket 10 wrenches orbits and to furthermore provide an attachment that can be used upsidedown or sidewiseas desired.

' further object of the invention is to provide, .in a mannerashereinafter set forth, a'device of the characterreferred to that isstrong, compactand durable, thoroughly reliable inits operation, veryefficient for its intended. purpose, very simple in its method ofassembly, and comparatively inexpensive to manufacture and operate.

With the foregoing and other objects in view the invention consists of anovel construction, combination and arrangement of parts which will behereinafter more specifi- 35 cally' described and illustrated in theaccompanying drawings, wherein is disclosed an embodiment of theinvention, but it is to be understood that changes, variations andmodifications may be resorted to without de- 80 parting from the spiritof the claim hereunto appended.

In the drawings, wherein like reference characters denote correspondingparts throughout the several views:

Figure 1 is a front elevation of the brace in accordance with thepresent invention,

Figure 2 is a side elevation thereof,

Figure 3 is a vertical detailed sectional view taken substantially onthe line 33 of Figure 1,

Figure 4 is an inner face view of the cover late p Figure 5 is afragmentary plan view of the casing, I

Figure 6 is a vertical sectional view in detail of the grippingattachment for screw drivers, bits or the like.

Referring to the drawings in detail, 7 indicates generally the bracewhich includes an elongated shank 8 merging at its upper end in thecrank arm 9 and the crank arm in turn merging with an upstanding handle10. On the free end of the handle 10 is the customary knob 11 whiler'otatably supported on the crank 9 is a sleeve 12.

Supported on the lower end of the shank 8, in a manner presently to bedescribed, is a circular casing indicated at 13 formed in the centerwith a circular depression or pocket 14. Surrounding the pocket 14 is anupstanding side wall 15 and on the outer face of the side wall 15 thereis provided a plurality of 'radially'extending notches 16. The casing isformed with an open top and a solid" inner wall 17 the latter of whichmerges with the upstanding side walls 15..

The inner wall 17 is formed with a slot 1S that communicates with thepocket 14. On the outer face of the inner wall 17 there is formed anenlarged boss 19 provided with a horizontally extending opening 20 thatcommunicates with the pocket 14 to provide a bearing for the spindle tobe presently described.

The boss 19 is further provided with a recess or cavity 21 which opensinto the slot 18 and extends at right angles to the opening 20 for thepurpose of forming a bearing for the lower'end of the shank 8.Projecting vertically from the casing13 and formed integral therewith is.a tubular sleeve 22 slotted intermediate its ends as at '23. v

Projecting laterally from the upper end of the sleeve 22 is a handle 24to be used in steadying the brace while it is being used.

The cover plate is indicated generally at 25 and is substantially a fiatplate in the configuration of a horse-shoe formed on the inner face atthe margin with an inwardly directed pin 26 that is adapted todetachably seat in any of the series of grooves 16.

, From the center, of the inner face of the plate 25 there is formed aninwardly project ing spindle 27 that extends through the opening 20 andhas the outer end thereof reduced and threaded as at 28. A washer 29 isdisposedabout the reduced end 28 of the spindle, and is held'in tightabutment with the face of the boss 19 by a wing nut that engages with te thread d en .28.

'13. The cover plate is held in detachable relationby screwing the wingnut on the spindle 27. i There is acircular opening 32 in T the coverplate that extendsirom the slot 31 I through its' lower' edge. -The topwall of slot is l dcwitha circular recess or cavity 33... J V
